where:
[Note 6] = number of cylinders of LUSE composed by OPEN-K/3/8/9/E
CVS volumes specified by SVP or remote console.
[Note 5] = number of cylinders of OPEN-K/3/8/9/E CVS specified by SVP
or the remote console.
[Note 4] = number of blocks of CVS volumes calculated by:
[Note 5] × (number of head) × (number of sectors per track)
OPEN-9 CVS, which has 6676 cylinders. To calculate the value of [Note 2]:
[Note 4] = 6676 × 15 × 96 = 9613440
([Note 4]/(2048 × 1016)) = (9613440/(2048 × 1016)) = 4.62
[Note 2] = ↑4.62 to 2n↑ = 8
3. The value of [Note 3] is the size of the file system. Confirm the number of free
physical partitions and the size of the physical partition. For example, enter
lsvg <HP_disk_array>vg0
Calculate the maximum size of the file system using the following equation:
Maximum size of file system = (Free PPs – 1) × (PP Size) × 2048
where:
Free PPs = the number of free physical partitions
PP Size = the size of physical partition
Using the information obtained from the lsvg <HP_disk_array>vg0 command on
an OPEN-3*20 device, use the following calculation:
Maximum size of file system = (Free PPs – 1) × (PP Size) × 2048
(733 – 1) × 64 × 2048 = 95944704
95944704 is maximum size of file system for OPEN-3*20.

4. The value of [Note 4] is the number of blocks of CVS volumes. This number is
